[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...

Due to its large dynamic range, the decibel is a useful unit of measure and is used in various applications, mainly in the ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...

Building upon the Pipelined Frequency Transform (PFT) architecture, we have developed a new filter-bank technique that allows asymmetrical-band splitting of a given spectrum of frequencies. A few ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...
